STREET-CLEANING EQUIPMENT.

naeeaes.

To all whom t may concern.'

Be it known that I, HENRY PEZZETTI, a subject of the King of italy (having declared his intention of becoming a citizen of the United States), and residing at Phila-` delphia, inthe county of Philadelphia and,-

State of Pennsylvania, have invented ya new and useful Street-Cleaning Equipment, of which the following is a specification.

rhe equipment required for cleaning streets without the employment of excessive labor is very expensive and when less eX-l pensive equipment is employed, the labor charge is greatly increased. As a rule the sweepings have to be transported for a considerable distance and if this is done byl means of a self-loading sweeper it has-to travel away from its work of sweeping in order to be dumpedso that many sweepers are required. If the sweeper is unloaded on the street or merely collects the sweepings on the street, labor is required to load the sweepings into vehicles that can go to some suitable place and dum them, and if the sweeper after having iloaded itself with sweepings goes to some place to dump them, its sweeping operations are interrupted and in order to avoid delay in going to dumping grounds the expense of central stations where sweepings are transferred from one vehicle to another has, in some cases, been incurred.

The principal object of the present invention is to avoid the above mentioned and other defects and disadvantages and to provide street cleaning equipment which will be comparatively inexpensive, operative with a minimum of labor, and efficient.

rlhe invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it chosen for illustration in the accompanying draw ings forming part hereof and in which- Figures 1 and 2, taken together, are side views of apparatus constituting equipment of the invention, the same truck being shown in each figure.

Fig. 3, is a top or plan view of the portion of the equipment shown in Fig. 1.

Fig. 4, is a diagrammatic view, principally in longitudinal section showing fea,- tures of the dumping bodies, and

Fig. 5, is an elevational view of the lefthand end of the same showing the body in normal positionand parts of the chassis in section.

in the drawings l, is a Sel'fgloadng sweeper chassis.v `The 'revolving brush 2,y Y Vand chute 3, indicate portions of sweeping and lself-lofading mechanism.y 4, is a wheeled trucl'c and 5, 1s a lorry chassis. |The pla-teo, y

forms 6, 8 `and 7,*of the chassis 1v and 5, and.`

the chassis 1 and 5. 9, is one of a set ofv vbodies transferable between the .chassis 1 ,truck respectively, are at substantially vthe same level andthe capa'cityofthe truck 'platform is greater than the; capacities of and 5, by way of the'truck 4, which accom. i

modates a full and an empty body at the same time. The sweeper chassis is provided with body shifting gear 10, and the lorry chassis is providedwith body shifting geary 11. The shifting gear in each case comprises a chain 12, wound in opposite directions around an operating shaft 13, and

adapted to shift a jointed wheeled carriage 14, provided on each of the bodies. When the free part- 14?, of the carriageA is con-v nected with its body as by means of the catch 15, Fig. 5, the body can be wheeled about on thev various platforms, and by releasing the catch 15, thebody can beV dumped, Fig. 4( The mechanism 16, when automatically .operates the tail 17, are fastenings for preventing present board.

undesirable relative movement of the'truck" and chassis, and 18, Vis a draw-bar connec-` f tion by which the sweeper can tow the truck. y f i In use an empty body 9, is always prof vided'on the truck 4, and the truck is' stationed on the street near where the sweeper 1, is at work. vThe sweeper cleans the street and loadsthe body 9, then arranged on it and when this body is full the sweeper and truck arel relatively placed as shown in Fig.

3, and the full body is transferred to the truck, use being made of the fastenings 12',4

and shifting gear 10, Afor this purpose.A

The relative position of the sweeper and" truck are then shifted for example by pulling the truck along andthe empty body isfi transferred to the sweeper which continues` to "ed from one convenient locality to anolier as the worlr progresses. The rails 19, serve to prevent detachment of the bodies from ille chassis.v

l claim: l. in street cleaning equipment the conibinasion of lie chassis of a self-loading sweeper alie chassis of a lorr a oluralic i of carriages each provided With Wheels and with a joint, provisions on eacli or" 'che chassis for receiving and holding said carriages singly, a truck adapt-ed to rece-ive Asaid carriages in mltiple, means on each chassis for transferring said carriages to and from 'the truck, bodies carried by said carriages and attached 'to the carriages kso one side of Jolie joint, and devices on the lorry chassis for Working Jdie joinl'J of a carriage to dump its body, substantially as described.

2. In stree; cleaning equipment the combination of Wheeled carriages consisting of two parts, a joint between said parts, dumping bodies connected with one of the parts of the Acarriages and provided with means scri-bed.
